At a grocery store, Rick bought 4 loaves of bread and 3 gallons of milk for $20. Danny bought 6 loaves of bread and 2 gallons of milk for $25. Identify the cost of a loaf of bread and a gallon of milk
Hey there! I'm happy to help!
Let's call the cost of a bread loaf b and the cost of a milk gallon m. Here is the info we have.
4b+3m=20
6b+2m=25
We solve one equation for b or m (we will solve the first one for b.
4b+3m=20
Subtract 3m from both sides.
4b=20-3m
We divide both sides by 4.
b=5-3/4m
We plug this value of b into the second equation to solve for m.
6(5-3/4m)+2m=25
We use distributive property to undo the parentheses.
30-4.5m+2m=25
We combine like terms.
30-2.5m=25
We subtract 30 from both sides.
-2.5m=-5
We divide both sides by -2.5
m=2
We plug this m into one of the original equations to find b.
4b+3(2)=20
4b+6=20
Subtract 6 from both sides.
4b=14
Divide both sides by 4.
b=3.5
So, a loaf of bread costs $3.50 and a gallon of milk costs $2.00.

Answer:
[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
Step 1. Turn the second fraction upside down (it becomes a reciprocal):
[tex]\frac{4}{5}[/tex] becomes [tex]\frac{5}{4}[/tex]
Step 2. Multiply the first fraction by that reciprocal:
[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = ?
3 x 5 = 15
7 x 4 = 28
[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = [tex]\frac{15}{28}[/tex]
Step 3. Simplify the fraction:
[tex]\frac{15}{28}[/tex] = [tex]\frac{15}{28}[/tex] You can't simplify this fraction
Answer:

Aliaa uses deductive reasoning to identify the number angles that fit inside a circle based on her knowledge that obtuse angles have measures greater than and that there are at the center of the circle. Aliaa wants to partition the circle in 3 congruent angles, what is the angle measurement that best fits Aliaa's circle partition?
Answer:
The best angle measurement that best fits Aliaa's circle partition is three angles of 120° each.
Step-by-step explanation:
The sum of angles at the center of the circle = The sum of angles at a point = 360°
Therefore, to partition the circle into three congruent angles, the measurement of each of the partition should be 360°/3 = 120°
The steps to partition a circle into three are;
1) Draw the diameter of the circle, to intersect the circumference of the circle at points A and B
2) Mark a point, C, at a distance of half the radius from the center of the circle, O, to the point, B, on the circumference, using a straight edge
3) Draw a perpendicular line to the diameter of the circle, through the point, C, to intersect the circle circumference at points D and E)
4) Draw radial lines from the circle center, O, to the points D and E
5) The segments OA, OB, and OE, are segment lines partitioning the segment into three congruent angles.

It rained 0.84 inches on Saturday and 0.8 inches on Sunday. How much did it rain on Saturday and Sunday combined?
Answer:
1.64
Step-by-step explanation:
The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).
0.84
+0.80
Then bring down the decimal point into the answer column, and add like normal.

Alex rolls a six-sided number cube 570 times. Approximately how many times can he expect to roll a 5?
Answer:
95 times
Step-by-step explanation:
Probability of rolling a 5 =1/6
So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times
1)First determine the probability of rolling a 5
2)Since you can only roll a 5 once in a 6-sided cube the probability is ⅙ or about 0.1667
3)Multiply the probability and the total number of rolls
.1667 * 570= 95
Answer : 95 times

Step-by-step explanation:
Use a calculator:

and √15 is between √9 and √16 you can say √15 is between 3 and 4
Solve for n. 11(n – 1) + 35 = 3n
11n - 11 + 35 = 3n
8n = - 24
n = - 3
Answer:
n = -3Step-by-step explanation:
Simplifying
11(n + -1) + 35 = 3n
Reorder the terms:
11(-1 + n) + 35 = 3n
(-1 * 11 + n * 11) + 35 = 3n
(-11 + 11n) + 35 = 3n
Reorder the terms:
-11 + 35 + 11n = 3n
Combine like terms: -11 + 35 = 24
24 + 11n = 3n
Solving
24 + 11n = 3n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-3n' to each side of the equation.
24 + 11n + -3n = 3n + -3n
Combine like terms: 11n + -3n = 8n
24 + 8n = 3n + -3n
Combine like terms: 3n + -3n = 0
24 + 8n = 0
Add '-24' to each side of the equation.
24 + -24 + 8n = 0 + -24
Combine like terms: 24 + -24 = 0
0 + 8n = 0 + -24
8n = 0 + -24
Combine like terms: 0 + -24 = -24
8n = -24
Divide each side by '8'.
n = -3
Simplifying
n = -3

Please help on number 9 and 10. Will mark brainliest.
Answer:
9. 1.24 mL
10. $5.93
Step-by-step explanation:
Question 9:
If the dosage of medicine is 0.01 mL per pound of weight of the patient, and the patient's weight is 124 pounds, we can set up an equation to solve for how much medicine the patient would need to take:
Dosage of medicine per pound of body weight x Total body weight = Total medicine required
OR
0.01 * w = m,
where w is total body weight and m is total medicine required.
To solve for the dosage the patient needs, just plug the numbers into the right places (124 for w and leave m as it is):
0.01 * 124 = m
1.24 = m
Therefore, a patient with a body weight of 124 pounds would need a 1.24 mL dosage.
Question 10:
To make the multiplication easier, we could rewrite 15% as 0.15 ( because 15% = 15/100):
0.15 * Total bill = Total tax payed for bill (Also can be written as [tex]\frac{15}{100} * 39.51[/tex])
OR
0.15*39.51 = Total tax
5.9265 = Total tax
5.93 = Total tax <-------- (rounded)
